Consider an iron cube and an aluminum cube. If the two cubes were at the same temperature, how would the average kinetic energy of the particles in iron compare with the average kinetic energy of the particles in aluminum?
1 answer
In a gas, the average kinetic energies would be the same, independent of atomic of molecular mass. In a metal, the situation is more complex. There are specific heat differences and "Debye temperature" differences to worry about. The teacher who assigned this question may not be aware of this fact.
